Textures in cycles are black
The bridge is showing up as black because it has no shader on it. You need to add a shader to it to be able to render it. Let's use a diffuse shader.


In the node editor, Shift A Shader -> Diffuse
Connect the output from the Hue node to the color input of the diffuse shader.
Connect the BSDF output from the diffuse shader to the Material Output's Surface input.
